ing the apparatus. With this type of apparatus it is most desirable toprovide a type of connection that is not liable to get out of order withunskilled use. Moreover, the easy swivel movement both of the tool andconnecting hose is required for insuring the best results in cleaning aswell as for convenient handling of the hose and suction cleaning tool.

The essentials of the instant ,coupling mechanism, provided for twocylindrical telescoping members, are registering exterior and interiorannular slots or grooves in association with an annular resilient,coupling member or wire normally flattened 0n opposite sides in anelliptic form to be positioned in connecting relation within portions ofboth-of these slots or grooves, whereby the telescoping members areretained in swiveled relation for use. The resilient coupling member isprovided with means for flexing the flattened sides outward for forcingit into the groove in the outer member so as to clear the opposinggroove in. the inner member and permit the separation of the connectedtelescoping members.

The features of my improved construction and the preferred embodimentand use may best be explained in connection withthe ac companyingdrawings, wherein:

[Figure 1 is an end View of'the exterior telescoping connecter member,".1 Fig. 2 is a view in'elevation of the hose terf minal and connecter,

Fig. 3 is a-vertical section. on line 33, Fig.

Fig. 4 is a similar section showing the connecter wire retracted withinthe groove for releasing the normally connected members, Fig. 5 is afragmentary longitudinal section on line 5-'5, F ig. 1,

Fig. 6 is a view in elevation, partially broken away and in section, toillustrate the swivel connection of the hose with an attaching membertherefor, and

Fig. 7 is a view in side elevation of a suction tool comprising a nozzleand brush adapted to be removably connected at the end of the hose,

Throughout the several figures of the drawings I have employed the samecharacter of reference to indicate similar parts.

.One or both ends of the hose a may be provided with the outer tubularswivel connecter member I), as shown in Figs. 2 and 6.

As best indicated in Figs. 3 and 4, said tubular member I) is providedwith an interior slot .01 groove b',adapted to accommodate the resilientwire loop connecter 0 normally having the elliptical form flattened onop posite sides, as indicated in Figs. 1 and 3, so that the sides of theellipse will lie inside the bore of the outer tubular member I). Theends of the wire 0 are firmly connected to a forked yoke c positionedabove the open slotted portion b covered by the housing d, through whichthe actuating stem 0" pro trudes. Upon the depression of this stem, asin Fig. 4, the wire loop 0 immediately is flexed outward to assumesubstantially circular form entirely within the slot or groove 6', flushwith the interior bore of member 6.

The inner telescoping member, two different types of which are shownrespectively in Figs. 6 and 7, preferably is provided with a tubularportion 6 or f terminally beveled at e or f and annular grooved orslotted at e" 'or f at a distance therefrom, respectively.

groove e and afiords a swivel connection for these parts that mayreadily be released, as

ulre it will be appreciated that the tool of Fig. 7, comprising asuction nozzle 7 and a slotted: removable brush 7 positioned forwardlyof the tubular portion f, may be inserted in the opposite end of thehose which we may assume is shown in Figs. 1, 2 and 5; the connectingmeans being identical, however, at both ends of the hose. The annularslot or groove f" would be similarly engaged by the wire loop 0 normallyoccupying a portion only of the groove 6 1n the outer tubular member, sothat the tool is afi'orded temporary swivel connection permitting it toassume automatically various cleaning positions'to conform with thehanging, upholstery, or othersur- "face being cleaned. Obviously, thetool may quickly be removed and re laced by another tool similarlyconstructed r insertion within the connecter member. p Having nowdescribed the preferred'embodiment of my invention, together with itspresent adaptation, advantages and use, I claim as new and desire tosecure .by Letters Patent, the following:

1. The combination of outer. and inner cylindricaltelescoping members,there being an interior annular groove in the outer memher and anexterior annular registering groove in the inner member, a'connectingmember for said telescoping members comprising a single annularelliptical shaped 35 resilient wire'loop for engaging in portions ofeach of the grooves, and operating means secured to said connectingmember for temporarily flexing the sides of the loop outwardly into thegroove of the outer member, 40 to permit a separation of the telescopinmembers. a

2. The combination of outer and inner cylindrical telescoping members,there being an interior annular groove in the outer member 45 and anexterior annular registering groove in the inner member, a connectingmember f or saidtelescopiil members comprising a smgle annularelliptical shaped resilient wire loop for engaging in portions of eachof the m grooves, and a forked'yoke secured to the wire loop fortemporarily flexing the flat tened sides of the loop outward into thegroove of the outer member to ermit a separation of the telescopin memers.

.In testimony whereof Ido now afiix my signature. EUGENE F. MARTINET.
